Anti-blocking atrial drainage tube

Abstract

The invention relates to an anti-blocking atrial drainage tube, belonging to the technical field of medical devices. The anti-blocking atrial drainage tube comprises a tube head and a tube body; the tube head is spherical or ellipsoidal in shape, the outer surface of the tube head is alternately distributed by protrusions and depressions, and a plurality of drainage holes for liquid to enter intothe tube head are arranged at the depressions. As the anti-blocking atrial drainage tube of the invention is used, the metal tube head can be naturally stabilized at the low part of the operation field under the joint action of the gravity and the flexible tube body, and since the tube head of the invention has no spring structure, the tissue cannot be pinched, and the occurrence of damage is reduced.

Description

technical field [0001] The invention relates to an anti-clogging atrial drainage tube, which belongs to the technical field of medical devices. Background technique [0002] The atrial drainage tube is a necessary material for cardiopulmonary bypass surgery. The atrial drainage tube in the prior art is generally composed of a tube body made of silica gel and a head end made of metal. There are also types made of silica gel or wound with metal wires. The drainage tube formed by the metal spring head end has three problems in the actual use of this drainage tube. First: Because the head end made of spring wire is not enough in weight, it is difficult to maintain the lowest position in the surgical field during surgery, and the fluid that needs to be drained is generally gathered at the lowest position in the body cavity due to gravity, so the drainage effect is not good. Not good; second: because the spring wire is denser, it is easy to be blocked by tissue during drainage, r...

AI Technical Summary

Problems solved by technology

[0003] The present invention increases the weight of the head end by changing the spring wire at the head end of the existing drainage tube into a spherical or ellipsoidal head, and the outer surface of the head is alternately distributed with protrusions and depressions, and the drainage holes are located in the depressions. the above problem
